Absolutely this requires a cost-benefits analysis! So, what is the false positive rate? I pulled the 100-to-1 out of my ass. Maybe it's 10K-to-1 or only 5-to-1

Absolutely this requires a cost-benefits analysis! So, what is the false positive rate? I pulled the 100-to-1 out of my ass. Maybe it's 10K-to-1 or only 5-to-1. Maybe the false negative rate is 19-to-1, which would also make it rather useless. Dunno. Does the school know? Is that information public? Sure would be nice to have, yes? What does "inconvenience" mean? I think you're talking about inconvenience for the students. If so, I want you to consider what "inconvenience" means for the school administration. They have many policies they could enforce. They could have mandatory campus-wide testing every three days, and if someone tests positive then the campus is closed until tests are negative for three weeks, and during that time all on-campus residents are in quarantine, and classes switch to 100% remote teaching. Inconvenient, yes? But if the question is simply "Inconvenience vs serious health problems or death" then surely this inconvenience they could put up with, yes? It'll surely be more effective than this BioButton! Instead, it sounds like the administration wants something which is more convenient and cheaper to their budget. If so, shouldn't they demonstrate that this convenience isn't some sort of high-tech smoke&mirrors to avoid paying for something that is actually effective?
